IOC Mr. A. R. Wallace on certain species of Corvus. 
P. 330. For Charadrius mongolicus read Charadrius longipes ,—- 
the true Charadrius mongolicus of Pallas being a Hiaticula —the 
same as H. ruficollis, Blyth, of India, according to Mr. Swinhoe. 
P. 331. The Snipe included in my list has been compared 
with specimens of Gallinago solitaria of Hodgson, but it certainly 
is not of that species, being entirely devoid of the white patches on 
the back and wings, and of a generally lighter colour. It seems 
to agree with Mr. Gould's G. australis , the only differences 
being its slightly inferior size and more reddish hue. The sex of 
my specimen is doubtful; its length is 123 in., that of the wing 
5-8 in. I may remark, that the figure in the ‘ Fauna Japonica' 
(pi. 68) looks like an imperfect copy of G. solitai'ia } and may 
(though it would not be fair to assume such as the case) have 
been taken from a specimen not killed in Japan. 
P. 331. Podiceps auritus should stand as Podiceps philippensis, 
being identical with Chinese specimens of that species. 
In conclusion, I must express my thanks to Dr. Sclater, Mr. 
J. H. Gurney, Mr. G. R. Gray, Mr. Gould, and Mr. Swinhoe, for 
the assistance they have so readily afforded me.

IX.— Note on Corvus senex, Gam / Less., and Corvus fusci- 
capillus, G. R. Gray. By Alfred R. Wallace, F.Z.S. 
On looking over SchlegePs ‘ Notice sur le genre Corvus ,' and 
comparing his figures and descriptions with my specimens from 
the Malay Archipelago, I was surprised to find that his Corvus 
senex was not Lesson's species, but a quite different bird, ob¬ 
tained by me at the Aru Islands, which Mr. G. R. Gray inserted 
in his list (Proc. Zool. Soc. 1858) as C. orru, but afterwards 
(on receiving the true C. orru from Dorey) named C.fuscicapillus. 
Schlegel's specimen appears to have been an immature female. It 
agrees exactly with mine in the high-arched bill, which is very 
much compressed, and in all the principal dimensions; but the 
adult birds have the plumage in both sexes purple-black, glossy 
above, except the head and neck, which are of a deep sooty brown. 
The face is thickly plumed; but in a young specimen which I
